If the reading is below 5.0 microamps, you have a bad flame sensor. On a maintance check you always check for flame rectification (flame sensing). You can measure flame signal by putting your meter (capable of measuring micro amps) in line between the flame sensor and the wire that was connected to it (see picture).

Watch The Furnace Ignite You Will See Spark Or Orange Glow In Front Of One Burner And The Flame Sensor Should Be On Opposite Side, But I Have Seen Them On The Next Burner From The Igniter.


This means you need to disconnect the wire from the rod, connect one multimeter lead to the rod and connect the other to the wire you removed from the rod. Rub the metal part (and no. If still not within range try a new rod and/or tighten grounding connections.
